NCube Corp has also introduced a low-cost turnkey interactive television development system designed to provide the same technology that is already used in the large-scale interactive television trials. The entry-level system, nVision, includes a deskside nCube media server and a set-top box from Apple Computer Inc. NVision is said to be scalable to as many as 200 video streams and provides the technology found in metro-class interactive television systems. It is compatible with media server software used at Bell Atlantic Corp and British Telecommunications Plc. The nCube media server provides 10Gb of storage, 16 input-output channels, a CT3 interface for T1 streams, and an Asynchronous Transfer Mode interface for E1 streams; prices go from $23,000.
